DETAILED DESCRIPTION

Reference will now be made in detail to the present embodiments of thedisclosure, examples of which are illustrated in the accompanyingdrawings. Wherever possible, the same reference numbers are used in thedrawings and the description to refer to the same or like parts.

FIG. 1 illustrates a perspective view of a mixed reality assemblyaccording to some embodiments of the present disclosure. As shown inFIG. 1, the mixed reality assembly includes a curved mirror 100 and aportable apparatus 400. The curved mirror 100 includes a concave surface110, a convex surface 120 opposite to the concave surface 110, and alight transmissive medium (not shown) between the concave surface 110and the convex surface 120. The portable apparatus 400 can be a portableapparatus having a display apparatus (not shown), such as a smartphoneor a tablet computer. The curved mirror 100 may be a spherical mirrorhaving a spherical diameter in a range from about 600 mm to about 1400mm or may be other suitable curved mirror which corresponds to a size ofthe portable apparatus 400. The portable apparatus 400 is in front ofthe concave surface 110 and within a focal length of the curved mirror100 at the time of use. In particular, a distance between the portableapparatus 400 and the concave surface 110 is less than a focal length ofthe curved mirror 100 (e.g., 60 cm). For example, the distance betweenthe portable apparatus 400 and the concave surface 110 is from about 20cm to about 50 cm. Applying the imaging principle of geometrical optics,when the portable apparatus 400 is within a focal length of the curvedmirror 100, the portable apparatus 400 and the displayed image will forman enlarged virtual image behind the curved mirror 100. Therefore, whenthe image of the portable apparatus 400 changes, the enlarged virtualimage will change as well. The embodiments of the present disclosureutilize changes in the enlarged virtual image to let the user have aninteraction experience, which will be discussed below.

FIGS. 2 and 3 illustrate an operation scenario of the mixed realityassembly shown in FIG. 1. In some embodiments, the portable apparatus400 includes a display apparatus 410 and a motion detection module 420.The display apparatus 410 has a display surface 412 facing the curvedmirror 100, and can display an image on the display surface 412. Theimage may also be referred to as a real image RI. The display surface412 of the display apparatus 410 is within the focal length of thecurved mirror 100, so an enlarged virtual image VI corresponding to thereal image RI is formed behind the curved mirror 100. That is to say,the pattern of the real image RI is the same as that of the enlargedvirtual image VI, while a size of the enlarged image VI is greater thanthat of the real image RI. For example, the enlarged virtual image VImay be a proportionally enlarged pattern of the real image RI. Themotion detection module 420 is configured to detect a motion of a realobject O in front of the display surface 412 (e.g., the real object Oillustrated in FIG. 3 moves in the direction of arrows on two sidesthereof in a side-to-side manner). The display apparatus 410 can changethe displayed real image RI according to the motion of the detected realobject O, and thereby change an enlarged virtual image VI behind thecurved mirror 100 (e.g., the enlarged virtual image V illustrated inFIG. 3 moves in the direction of arrows on two sides thereof in aside-to-side manner). The change of the enlarged virtual image VI isinduced by the motion of the real object O, such that the user can havean interaction experience of the enlarged virtual image VI and the realobject O. In addition, because the interaction perceived by the user isfrom the enlarged virtual image VI behind the curved mirror 100 and notfrom the real image RI displayed by the display apparatus 410, the usercan have a newer and more interesting interaction experience.

FIGS. 4 to 7 illustrate another operation scenario of the mixed realityassembly shown in FIG. 1. As shown in FIGS. 4 and 5, the real object Oais between the curved mirror 100 and the portable apparatus 400, and sothe real object Oa is within the focal length of the curved mirror 100.Therefore, the real object Oa is formed as an enlarged object virtualimage VOa corresponding to the real object Oa behind the curved mirror100. That is to say, an appearance of the enlarged object virtual imageVOa is the same as that of the real object Oa, while a size of theenlarged object virtual image VOa is greater than that of the realobject Oa. For example, the enlarged object virtual image VOa can be aproportionally enlarged pattern of the real object Oa. When the usermoves the real object Oa, the enlarged object virtual image VOa behindthe curved mirror 100 will move as well, and therefore the user caninteract with the virtual image VIa behind the curved mirror 100 formedcorrespondingly by the real image RIa of the display surface 412. Forexample, the real image RIa of the display surface 412 can be a staticimage (e.g., a static castle), and forms a static virtual image VIabehind the curved mirror 100. When the user moves the real object Oatoward the portable apparatus 400 (e.g., in the direction of the arrowshown in FIG. 4 to a position shown in FIG. 6), a distance between thereal object Oa and the curved mirror 100 increases, such that theenlarged object virtual image VOa is further enlarged (e.g., the patternshown in FIG. 5 is enlarged to the pattern shown in FIG. 7). As aresult, the user may have a new and more interesting interactionexperience.

FIG. 8 illustrates a block diagram of the portable apparatus 400 inaccordance with some embodiments of the present disclosure. As shown inFIG. 8, the portable apparatus 400 further includes a display controlmodule 430. The display control module 430 is electrically connected tothe motion detection module 420 and the display apparatus 410. Thedisplay control module 430 can produce electrical signals to controleach subpixel in the display apparatus 410. For example, when thedisplay apparatus 410 controls images by a thin film transistor (TFT)array substrate, the display control module 430 can produce electricalsignals to several scan lines and data lines in the display apparatus410, and thereby control electrical connection to the thin filmtransistor of any scan line and data line to control brightness anddarkness of the subpixels (e.g., red subpixel, green subpixel or yellowsubpixel) corresponding to the thin film transistor. When the motiondetection module 420 detects motion of the real object O (see FIG. 2),an electrical signal is produced correspondingly and transmitted to thedisplay control module 430. The electric signal is related to the traceof the motion of the real object O. The display control module 430 cancontrol the real image RI (see FIG. 2) displayed by the displayapparatus 410 by the electrical signal, and thereby controls the virtualimage VI (as shown in FIG. 2) behind the curved mirror 100. By usingsuch a method, the display control module 430 can change the real imageRI displayed by the display apparatus 410 according to the motion of thedetected real object O. Except the thin film transistor, the displayapparatus 410 may control image generation using other devices, such asquantum-dot-based LEDs or other suitable technique, but the presentdisclosure is not limited in this regard.

In addition, in some embodiments, the portable apparatus 400 furtherincludes a sound control module 440 and a speaker 450. The sound controlmodule 440 is electrically connected to the motion detection module 420and the speaker 450. The sound control module 440 may produce audiosignals to control the speaker 450 to produce sounds. When the motiondetection module 420 detects movement of the real object O (see FIG. 2),a corresponding audio signal is produced and transmitted to the speaker450. The audio signal is related to the trace of the motion of the realobject O. Therefore, the sound emitted by the speaker 450 or the changeof the sound is induced by the movement of the real object O, such thatthe user can feel the experience of the sound of the speaker 450interacting with the real object O. For example, when the user waves thereal object O rapidly, the motion detection module 420 can detect therapid moving trace of the motion and the sound control module 440 canthen provide a corresponding audio signal to the speaker 450 to make thespeaker 450 emit a sound related to such rapid motion according to theaudio signal.

In some embodiments, the motion detection module 420 includes an imagecapture apparatus, for example, a complementary metal oxidesemiconductor (CMOS) image capture device, a charge coupled device (CCD)image capture device, or another suitable device installed on theportable apparatus 400. Furthermore, in some embodiments, correspondingimage analysis software can be installed in the portable apparatus 400to analyze a trace of the motion of the real object O from the imagecaptured by the CMOS or CCD or identify an appearance of the real objectO. After identifying the appearance or the trace of the motion of thereal object O, the portable apparatus 400 inputs the identifiedinformation into an application program for image display to trigger acorresponding interaction process. The application program generates asubsequent image according to the internal storage of the portableapparatus 400 or a data dictionary of a remote database, or obtains thesubsequent image from the remote database to display so as to achieve aninteraction with the user.

In some embodiments, the motion detection module 420 is positionedfacing or facing away from the position of the curved mirror 100, orpositioned on two surfaces which are facing and facing away from thecurved mirror 100 simultaneously, such that the motion detection module420 can detect a trace of motion of the real object O and combine anidentifying software or hardware having function of facialidentification, gesture identification, voice identification or othertypes of identification such that a body movement, a gesture, a facialexpression, a voice or other behaviors of the user can be detected aswell. After a keyword is identified according to the behaviors of theuser, the keyword is input into the application program, a correspondingresource may be obtained by searching the keyword on internet, and acorresponding interactive content is generated or selected based on thesearch results and displayed on the portable apparatus 400. Theinteractive contents may include animations of characters which arestored in the portable apparatus 400, streamed from remote server, orgenerated in real-time. The displayed character may interact with theuser based on scripts and perform scenarios such as games, shows, talks,presentations, or any type of interaction activities. The scriptsinclude activities of the character and the requirements to trigger thefollowing or responding activities. The activities include animations ofthe character and visual effects and corresponding audio. The scriptsmay also include random activities or decision making rules orprocesses, which may make the character more real or human-like.

For example, when the user speaks out a title of a song to be played,the portable apparatus 400 automatically searches the song and acorresponding image/video and then displays such image/video and song.In other embodiments, a virtual character in the image/animation can askthe user a question or ask the user to make a choice. The motiondetection module 420 can identify a position of a face of the user andthen input the position of the face into the application program. Theapplication program adjusts a direction which the virtual characterfaces according to the position of the face of the user immediately.After virtual character asks the question or asks the user to make thechoice, possible answers or selections may be displayed, such that theuser can utilize the real object O or a body movement to aim at one ofthe answers or selections. The user may also make a gesture, speak out adesired selection or perform other suitable expressions to response thevirtual character. The response of the user is detected and identified,and the result is input into the application program. After that, theapplication program begins to display image/video content related to theuser's selection or generate a subsequent image/video content to bedisplayed.

In some embodiments, the mixed reality apparatus may be combined withconnected Artificial Intelligence (AI) platforms to process naturallanguages. After the portable apparatus 400 receives a voice of theuser, the voice is processed to identify the message and thentransmitted to the cloud to be analyzed the meaning thereof. Afterresponse information is generated by the cloud, the response informationis transmitted back to the portable apparatus 400. The responseinformation includes image/video content corresponding to the voicereceived by the portable apparatus 400 which will be displayed by theportable apparatus 400, or image/video generation informationcorresponding to the voice where the portable apparatus 400 will utilizethe image/video generation information to generate image/video content.As mentioned above, the application program on the portable apparatuscan generate selections/answers and display an image/video to ask theuser to make a choice. Rather than waiting for the user to operate, theapplication program combined with connected Artificial Intelligence (AI)platform can also actively provide options of conversation topics to theuser. After the user select one of the topics, the application programcombined with connected Artificial Intelligence (AI) platform displays acorresponding content or starts a conversation related to the topic withthe user. The application program combined with connected ArtificialIntelligence (AI) platform can actively search information related tothe user, such as information from social networks, self-media orportable apparatus so as to generate options of conversation topics fora specific user. The audio content from connected ArtificialIntelligence (AI) platform may be used for generating correspondingfacial expression, such as mouth movement of the displayed character, sothat the user can feel the character in the displayed image/video saysthe words. The tone and wording are adjusted to fit the character of thedisplayed image. Search results may be integrated or modified to formtext-to-speech content to show to the user. The connected ArtificialIntelligence (AI) platform generates the feedback message based on therecognized keyword and analyzed result of the user's message or request.The processing of connected Artificial Intelligence (AI) platform couldbe performed in remote server, wherein the application installed inportable apparatus 400 retrieves message or request from the user, sendsthem to the remote server, retrieves the feedback message generated bythe server, and generates animation of the displayed character accordingto the feedback message. The feedback message may include onlineinformation or services possibly corresponding to the user's requests.

In some embodiments, the motion detection module 420 can detect a motionof the real object and the motion of the virtual image VI behind thecurved mirror 100. For example, when the motion detection module 420includes a CMOS, CCD or another image capture apparatus, the imageanalysis software installed in the portable apparatus 400 can not onlyanalyze a trace of the motion of the real object O from the imagecaptured by the CMOS or CCD but also analyze a position and/or trace ofthe motion of the virtual image VI as well. Therefore, the displaycontrol module 430 can control the real image RI displayed by thedisplay apparatus 410 according to the motion of the real object O andthe virtual image VI detected by the motion detection module 420, andthus produces more possible interaction applications. For example, asshown in the scenario in FIG. 3, when the motion detection module 420detects and determines that the real object O overlaps hair of thevirtual character in virtual image VI, the display control module 430can modify the hair of the virtual character in the real image RIdisplayed by the display apparatus 410 (e.g., make the hair of thevirtual character in the real image RI seem to be touched).

Furthermore, in some embodiments, when the motion detection module 420includes a CMOS, CCD or another image capture apparatus, the imageanalysis software installed in the portable apparatus 400 can analyze abrightness of the virtual image VI by the image captured by the CMOS orCCD. The virtual image VI is formed by the real image RI which isdisplayed by the display apparatus 410, so the brightness of the virtualimage VI depends on the brightness of the real image RI displayed by thedisplay apparatus 410. Therefore, the portable apparatus 400 can changethe brightness setting of the real image RI according to the brightnessof the virtual image VI captured by the motion detection module 420, sothe brightness of the virtual image VI is optimized automatically.Besides, different users may prefer different brightness settings andthe portable apparatus 400 may detect identity of the current user andloads associated setting to application, so the images are displayed inproper settings to the specific user.

In some embodiments, the motion detection module 420 may include awireless signal receiver, and the real object O has a wireless signalemitter. Therefore, the motion detection module 420 can determine aposition and/or a trace of the motion of the real object O by thereceived wireless signal. For example, the motion detection module 420may be a radio frequency identification (RFID) module, and the realobject O can have an electrical label which can be identified by theRFID module so as to access information of the corresponding real objectO. For example, the real object O is a physical product with anelectrical label. After the motion detection module 420 identifies theelectrical label, the portable apparatus 400 can connect to the internetand access information corresponding to the electrical label of thephysical product, such as product specification, interaction video,image, or other product related information or contents, so the portableapparatus 400 can generate or display interacting contents associated tothe real object O, such as image, video, or audio signals, or theportable apparatus 400 can initialize a game associated to the realobject O. After the motion detection module 420 identifies theelectrical label, the usage status of the real object O may also beretrieved. For example, if the real object O is not sold or rented, thedisplay apparatus 410 can display corresponding options to the user,such as purchasing or renting the real object O. The user may decidewhether to pay for the right to own or rent the real object O. Thedisplay apparatus 410 can also display introductions of additionalcontents corresponding to the real object O to the user, so the user canchoose whether to download or pay for additional downloadable contentswhich is associated to the real object O.

In some embodiments, the display control module 430 and/or sound controlmodule 440 can be realized by hardware, software or firmware. Forexample, the display control module 430 and the sound control module 440can be integrated in a single application-specific integrated circuit(ASIC) or can be realized by different ASICs. Alternatively, the displaycontrol module 430 and/or sound control module 440 can be software orfirmware installed in the portable apparatus 400.

FIG. 9 illustrates a fragmentary enlarged view of the curved mirror 100in accordance with some embodiments of the present disclosure. As shownin FIG. 9, in some embodiments, the curved mirror 100 includes a lighttransmissive medium 130 between the concave surface 110 and the convexsurface 120. The light transmissive medium 130 may include glass orpolycarbonate (PC), but the present disclosure is not limited in thisregard. The curved mirror 100 is light transmissive and thus can allowthe user to view the virtual image behind the curved mirror 100 mixedwith the real environment. In some embodiments, the mixed realityassembly further includes an optical film 140. The optical film 140 isdisposed along the concave surface 110 of the curved mirror 100, forexample, the optical film 140 is coated on the concave surface 110. Thatis to say, the main surface (that is, the surface having the greatestarea) of the optical film 140 has a curvature that is substantially thesame as that of the concave surface 110, which is beneficial to form thevirtual image. The material of the optical film 140 is selected suchthat the transmittance and/or reflectance of the optical film 140 aidsin the formation of more viewable virtual images. For example, thematerial of the optical film 140 can be any light transmissive materialhaving a transmittance in a range from about 30% to about 60% or areflection ratio from about 30% to about 70%. In particular, thematerial of the optical film 140 may be any light transmissive materialhaving a transmittance in a range from about 35% to about 45% or areflectance ratio in a range from about 40% to about 60%. In someembodiments, the transmittance and/or the reflectance ratio of theoptical film 140 is changeable, so that the user can adjust thetransmittance and/or reflectance ratio of the optical film 140 accordingto the actual visual feel behind the curved mirror 100, and thereforethe virtual image is visually optimized for the user. For example, insome embodiments, the transmittance and/or reflectance ratio of theoptical film 140 can be adjusted by a current applied to the opticalfilm 140.

Referring back to FIG. 1, in some embodiments, the mixed realityassembly further includes a first holder 210, a second holder 220 and abase 300. The first holder 210 and the second holder 220 are disposed onthe base 300. The first holder 210 is configured to support the portableapparatus 400. Therefore, the first holder 210 is in front of theconcave surface 110 of the curved mirror 100 and within the focal lengthof the curved mirror 100, so that the portable apparatus 400 supportedby the first holder 210 can form an enlarged virtual image behind thecurved mirror 100. The second holder 220 is configured to support curvedmirror 100, and thus a distance between the second holder 220 and thefirst holder 210 is not greater than the focal length of the curvedmirror 100, so that the portable apparatus 400 can form an enlargedvirtual image behind the curved mirror 100 supported by the secondholder 220. For example, when the focal length of the adopted curvedmirror 100 is not greater than 60 cm, and the distance between the firstholder 210 and the second holder 220 is in a range from about 20 cm toabout 50 cm.

In some embodiments, the portable apparatus 400 is arranged demountablywith the first holder 210. Therefore, as shown in FIG. 10, the portableapparatus 400 can be separated from the first holder 210. In particular,the first holder 210 may include a front railing 212 and a back railing214. The front railing 212 is closer to the curved mirror 100 than theback railing 214. The front railing 212 and the back railing 214 definea first slot G1 therebetween. When the portable apparatus 400 is placedon the first holder 210, the portable apparatus 400 can be inserted intothe first slot G1 and constrained by the front railing 212 and the backrailing 214. Furthermore, the portable apparatus 400 can be extractedfrom the first slot G1, so that the portable apparatus 400 is releasedfrom constraint by the front railing 212 and the back railing 214 andcan be carried away by the user.

Furthermore, in some embodiments, the second holder 220 is arrangeddemountably with the base 300. Therefore, as shown in FIG. 10, thesecond holder 220 can separate from the base 300. For example, the base300 has a second slot G2. The second holder 220 can be inserted into thesecond slot G2 of the base 300 and be constrained by the base 300.Furthermore, the second holder 220 can be extracted from the second slotG2 and released from the constraint of base 300.

In some embodiments, the back railing 214 of the first holder 210 has asupport surface 214 s. The support surface 214 s is configured tosupport the back of the portable apparatus 400. As shown in FIG. 10, thesupport surface 214 s inclines relative to the base 300, so that thesupport surface 214 s can face the curved mirror 100. As a result, whenthe portable apparatus 400 is supported on the support surface 214 s,the display apparatus 410 of the portable apparatus 400 can display animage toward the curved mirror 100. As a result, the user facing thecurved mirror 100 can see that the virtual image of the image displayedby the portable apparatus 400 is shown on the curved mirror 100. Alength, a width, and a size of the curved mirror 100 are determinedbased on the requirements of the mixed reality assembly. In someembodiments, the curved mirror 100 has a long side and a short side andboth sides can be fixed on the second holder 220 alternatively. When theportable apparatus is placed horizontally on the first holder 210, thelong side of the curved mirror 100 is set in horizontal direction and isfixed on the second holder 220. When the portable apparatus is placedvertically on the first holder 210, the long side of the curved mirror100 is set in vertical direction and is fixed on the second holder 220.

In some embodiments, the mixed reality assembly has an improved viewingarea. When the portable apparatus 400 is fixed on the first holder 210,the view of the user at the improved viewing area is not sheltered orblocked, so the user can see the virtual image on the curved mirror 100fully and clearly. The display surface of the portable apparatus 400 andthe curved mirror 100 face each other with a certain angle, such thatthe curved mirror 100 can reflect the generated virtual image to theuser at the improved viewing area. In some embodiments, the portableapparatus 400 and the first holder 210 have an angle of elevation in arange from about 60 degrees to about 100 degrees. A bottom of the curvedmirror 100 and the second holder 220 maintain an angle of elevation in arange from about 60 degrees to about 100 degrees. In some embodiments,the first holder 210 makes the portable apparatus 400 fixed at a heightas measured from the table be in a range from about 50 mm to about 200mm. The second holder 220 fixes the curved mirror 100 at a suitableheight as measured from the table, which is related to the projectiondistance and an angle from the portable apparatus 400 to the curvedmirror 100, may be in a range from about 55 mm to about 400 mm, forexample, such that the inclined curved mirror 100 can directly face theinclined portable apparatus 400. Therefore, when the user views thevirtual image shown on the curved mirror 100, the user may feel that thevirtual image is positioned just on the table or very close to the tablerather than floats in air or sinks below the table. As a result, theuser can have an improved real visual experience. In some embodiments,the application of the portable apparatus 400 can adjust a position ofthe image displayed on the screen, so the user at the improved viewingarea can see the virtual image generated by the curved mirror 100 atproper position with proper height and size. In particular, theapplication can be set to mirror image displayed by the portableapparatus 400, i.e. the displayed image has opposite left and right. Asa result, the virtual image viewed by the user does not have oppositeleft and right caused by mirroring.

FIG. 11 illustrates a side view of the mixed reality assembly in someembodiments of the present disclosure. As shown in FIG. 11, the maindifference between the present embodiment and the above-mentionedembodiment is that the base 300 a of the present embodiment isstretchable so the length of the base 300 a is adjustable dynamically.Through such dynamic adjustment of the base 300 a, the distance betweenthe curved mirror 100 and the first holder 210, and the distance betweenthe curved mirror 100 and the portable apparatus 400 supported by thefirst holder 210 can be adjusted. Since the distance between theportable apparatus 400 and the curved mirror 100 can affect the size ofthe virtual image behind the curved mirror 100, the user can achieve thedesired size of the virtual image by dynamically adjusting the base 300a. For example, the base 300 a may include a first portion 310 and asecond portion 320. The second portion 320 can slidably couple to thefirst portion 310, and therefore, the user can pull the first portion310 and/or the second portion 320 outward to elongate the base 300 a toincrease the size of the virtual image, or push the first portion 310and/or the second portion 320 inward to shorten the base 300 a to reducethe size of the virtual image.

FIG. 12 illustrates a side view of the mixed reality assembly accordingto some embodiments of the present disclosure. As shown in FIG. 12, themain difference between the present embodiment and the above-mentionedembodiments is that the first holder 510 supporting the portableapparatus 400 is different from the above-mentioned first holder 210. Inparticular, the first holder 510 has a support surface 512 and a curvedsurface 514 extending from the support surface 512 downward to the base300. The support surface 512 touches and supports the portable apparatus400. The curved surface 514 is separated from the portable apparatus 400and is below a speaker opening 452 of the speaker 450 of the portableapparatus 400. When the speaker 450 emits sound through the speakeropening 452, the curved surface 514 of the first holder 510 can reflectthe sound wave toward the curved mirror 100, and then the curved mirror100 can reflect the sound wave reflected from the first holder 510 tothe user. In this way, the user will feel that the sound heard is fromthe curved mirror 100. Therefore, the mixed reality assembly of thepresent embodiment not only allows the user to view the virtual imagebehind the curved mirror 100, but also allows the user to hear soundfrom the curved mirror 100, thereby providing a full interactionexperience for the user.

FIG. 13 illustrates a block diagram of the mixed reality assembly inaccordance with some embodiments of the present disclosure. As shown inFIG. 13, the main difference between the present embodiment and theabove-mentioned embodiment is that the present embodiment furtherincludes an external speaker 600. The external speaker 600 is separatedfrom the portable apparatus 400 a and is wirelessly connected to theportable apparatus 400 a. Therefore, the external speaker 600 can bedisposed beside the curved mirror 100, so that the user can feel thatthe sound is from the curved mirror 100. For example, with reference toFIG. 14, the external speaker 600 may be placed below the curved mirror100 and separated from the first holder 510 and the portable apparatus400 a supported by the first holder 510. A speaker opening 602 of theexternal speaker 600 can emit sound toward the portable apparatus 400 a,so that when the user is positioned behind the portable apparatus 400 a,he or she feels that the sound comes from below the curved mirror 100,and therefore a more interesting interaction experience is provided tothe user.

In some embodiments, as shown in FIG. 13, the portable apparatus 400 aand the external speaker 600 include wireless transceiver modules 460and 610, respectively. The wireless transceiver modules 460 and 610 canbe wirelessly connected. For example, the wireless transceiver modules460 and 610 can be Bluetooth modules to transfer wireless signalsutilizing the BT frequency band to realize signal transmission.Therefore, when the image displayed by the portable apparatus 400 achanges, for example, the image moves or makes an action, the user maysee that the virtual image displayed by the curved mirror 100 changes.At the same time, the portable apparatus 400 a may produce correspondingaudio signal and transmit the same to the external speaker 600. Theexternal speaker 600 receives the audio signal from the portableapparatus 400 a and then broadcasts, such that the user can hear thesound corresponding to the virtual image simultaneously. In someembodiments, when the motion detection module 420 detects movement ofthe real object O (see FIG. 2), the sound control module 440 cangenerate a corresponding audio signal and transmit the same to thewireless transceiver module 610 of the external speaker 600 through thewireless transceiver module 460, such that the external speaker 600 canemit sound corresponding to the movement of the real object Osimultaneously.

In some embodiments, the speaker 450 of the portable apparatus 400 a orthe external speaker 600 can emit sound corresponding to the movement tothe real object O. The sound of the speaker 450 can be reflected to thecurved mirror 100 through the curved surface 514, and then reflected tothe user by the curved mirror 100. The user can feel that the sound isheard from the position of the external speaker 600 below the curvedmirror 100 or can feel that the sound is heard from the curved mirror100. In other embodiments, when the external speaker 600 emits sound,the speaker 450 of the portable apparatus 400 a may be kept silent, orthe speaker 450 emits sounds of additional sound channel to producestereo sound effect. Whether to emit the sound from the speaker 450 andthe external speaker 600 is controlled by the sound control module 440.

FIGS. 15 and 16 illustrate side views of the mixed reality assembly fromdifferent orientations in accordance with some embodiments of thepresent disclosure. The main difference between the present disclosureand the above-mentioned embodiments is that the first holder 700supporting the portable apparatus 400 is different from theabove-mentioned first holders 210 and 510. In particular, the firstholder 700 includes a plurality of separators 710 separated from eachother. The separators 710 are configured to support a bottom surface 402of the portable apparatus 400. Furthermore, the speaker openings 452disposed on the bottom surface 402 of the portable apparatus 400 are atleast partially not shielded by the separators 710. By using such aconfiguration, the sound from the portable apparatus 400 is not blockedby the first holder 700 and passes through the space between theseparators 710.

In some embodiments, at least one of the separators 710 is disposedbetween the two speaker openings 452 of the portable apparatus 400, sothat the separator 710 can prevent the sound from the two speakeropenings 452 from interfering with each other. Furthermore, in someembodiments, the first holder 700 further includes a back railing 720. Asupport surface 722 of the back railing 720 is configured to support aback 404 of the portable apparatus 400. The separators 710 protrude fromthe back railing 720 at intervals. Therefore, the bottom surface 402 andthe back surface 404 of the portable apparatus 400 can be supported bythe separators 710 and the back railing 720, respectively. In someembodiments, the back railing 720 includes a curved surface 724. Thecurved surface 724 is positioned below the bottom surface 402 of theportable apparatus 400 to reflect sounds toward the curved mirror 100(see FIG. 14).

In some embodiments, the back railing 720 is disposed behind theportable apparatus 400 and the separators 710 are disposed under theportable apparatus, so the back railing 720 is farther away from thecurved mirror (see curved mirror 100 in FIG. 14) than the separators 710being. In some embodiments, a top of the back railing 720 is higher thantops of the separators 710 such that the back railing 720 and theseparators 710 abut the rear surface and the bottom surface of theportable apparatus, respectively.

FIGS. 17 and 18 illustrate side views from different orientations of themixed reality assembly in accordance with some embodiments of thepresent disclosure. The main difference between this embodiment and theembodiments shown in FIGS. 15 and 16 is that the first holder 700further includes a plurality of front railings 730. The front railings730 are arranged at intervals in front of the back railing 720. Thefront railings 730 and the back railings 720 can firmly hold theportable apparatus 400 therebetween. The front railing 730 is disposedin front of the portable apparatus 400 and the separators 710 aredisposed under the portable apparatus 400, so the front railing 730 iscloser to the curved mirror (see the curved mirror 100 in FIG. 14) thanthe separators 710 being. In some embodiments, a top of the frontrailing 730 is higher than tops of the separators 710 such that thefront railing 730 and the separators 710 abut the front surface and thebottom surface of the portable apparatus 400, respectively.

FIGS. 19 and 20 are perspective views of the mixed reality assemblyaccording to some embodiments of the present disclosure. As shown inFIGS. 19 and 20, the main difference between the present embodiment andthe above-mentioned embodiment is that the curved mirror 100 of thepresent embodiment is rotatable. For example, the mixed reality assemblycan include a hinge 230 connected to the second holder 220 and the base300 b such that the second holder 220 is pivotally connected to the base300 b and can rotate relative to the base 300 b. That is to say, anangle of the second holder 220 relative to the horizontal surface can bechanged. Therefore, the curved mirror 100 constrained by the secondholder 220 can rotate relative to the second holder 220. Therotatability of the curved mirror 100 can bring about at least twoadvantages. One advantage is that the rotation of the curved mirror 100can change or adjust a height of the virtual image behind the curvedmirror 100, such that the user can obtain a desired position of thevirtual image by rotating the curved mirror 100. Another advantage isthat the curved mirror 100 can rotate to lie on the base 300 b (as shownin FIG. 20) to increase the portability of the mixed reality assembly.Furthermore, when the curved mirror 100 lies on the base 300 b, theportable apparatus 400 can be stored below the curved mirror 100. Forexample, the base 300 b has a storage space S, which has a depth greaterthan a thickness of the portable apparatus 400. That is to say, thedepth of the storage space S is greater than the thickness of thetypical smartphone or tablet. Therefore, when the curved mirror 100 lieson the base 300 b, the portable apparatus 400 can be stored in thestorage space S of the base 300 b and will not touch the curved mirror100.

In some embodiments, the base 300 b has a protruding rib 330 between thefirst holder 210 and the second holder 220. The protruding rib 330 canprotrude from a bottom surface of the storage space S of the base 300 b.When the curved mirror 100 rotates to lie on the base 300 b, the secondholder 220 can contact the protruding rib 330 of the base 300 b and besupported by the protruding rib 330. Therefore, the protruding rib 330can prevent the second holder 220 from continuing to rotate downward andthereby avoid a rotation angle of the hinge 230 from exceeding anallowable range which could ultimately result in the hinge 230 breaking.In some embodiments, the distance between the first holder 210 and thesecond holder 220 is not less than (that is, greater than or equal to)the sum of the height of the curved mirror 100 and the height the secondholder 220. Therefore, when the curved mirror 100 lies on the base 300b, the curved mirror 100 does not touch the first holder 210. In someembodiments, the base 300 b further includes a clasping structure (notshown) configured to lock the curved mirror 100 when the curved mirror100 lies on the base 300 b.

FIGS. 21 and 22 illustrate perspective views of the mixed realityassembly according to some embodiments of the present disclosure. Asshown in FIGS. 21 and 22, the main difference between present embodimentand the above-mentioned embodiments is that the mixed reality assemblyof the present embodiment further includes a wireless controller 800.The wireless controller 800 is arranged demountably with the base 300 c.For example, the base 300 c can include a hook 340 on a lateral surface301 of the base 300 c. The hook 340 can latch onto a slot (not shown) ofthe wireless controller 800 to fix together the base 300 c and thewireless controller 800. The wireless controller 800 can control thereal image RI (see FIG. 2) displayed by the portable apparatus 400 a viawireless communication to control the virtual image VI (see FIG. 3)behind the curved mirror 100.

For example, as shown in the block diagram of FIG. 23, the portableapparatus 400 a and the wireless controller 800 include wirelesstransceiver modules 460 and 810, respectively. The wireless transceivermodules 460 and 810 can be wirelessly connected. For example, thewireless transceiver modules 460 and 810 can be Bluetooth modules torealize signal transmission using wireless signals in the BT frequencyband. The wireless controller 800 further includes a button 820 and asignal producing module 830 electrically connected to the button 820 andthe wireless transceiver module 810. Therefore, when the user pressesthe button 820 and induces the signal producing module 830 to producecorresponding control signals, the wireless transceiver module 810 cantransmit the control signals to the wireless transceiver module 460 ofthe portable apparatus 400 a. As a result, the display control module430 and the sound control module 440 of the portable apparatus 400 a canrespectively control the real image RI displayed by the displayapparatus 410 and the sound output by the speaker 450 according to thecontrol signals. The virtual image VI behind the curved mirror 100changes according to the real image RI displayed by the displayapparatus 410, such that when the user changes the real image RI by thewireless controller 800, the virtual image VI will change as well.Therefore, the user will have the experience that the virtual image VIis controllable with the wireless controller 800. In some embodiments,the signal producing module 830 can be realized by hardware, softwareand/or firmware.

FIGS. 24 and 25 are perspective views of the mixed reality assemblyaccording to some embodiments of the present disclosure. As shown inFIGS. 24 and 25, the main difference between the present embodiment andthe embodiments of FIGS. 21 and 22 is that configurations of thewireless controller 800 a and the base 300 d are different from those ofthe above-mentioned embodiment. In particular, as shown in FIGS. 24 and25, the base 300 d has a controller storage slot 302 on a top surface ofthe base 300 d. A size and a shape of the controller storage slot 302match the wireless controller 800 a, such that the wireless controller800 a can be stored in the controller storage slot 302.

FIGS. 26 and 27 are perspective views of the mixed reality assemblyaccording to some embodiments of the present disclosure. As shown inFIGS. 26 and 27, the main difference between the present embodiment andthe above-mentioned embodiments is that the back railing 214 a of thefirst holder 210 a is movable relative to the front railing 212. Inparticular, the back railing 214 a is in a recess portion 303 of thebase 300 e. The mixed reality assembly includes a plurality of firstscrews 910 penetrating through the back railing 214 a and fastened tothe recess portion 303 of the base 300 e. Therefore, when the firstscrews 910 are loosened, the user can move the back railing 214 abackward and forward to control the distance between the back railing214 a and the front railing 212. When the portable apparatus is placedbetween the front railing 212 and the back railing 214 a, the user cantighten the first screws 910 to fix the portable apparatus. By usingsuch a configuration, the mixed reality assembly is suitable for usewith portable apparatuses having different thicknesses.

Furthermore, in some embodiments, the mixed reality assembly furtherincludes a second screw 920 fastened to the top surface 304 of the base300 e. The user can rotate the second screw 920 to change a protrudingheight of the second screw 920 on the top surface 304. As a result, whenthe second holder 220 is rotated about the hinge 230 by a certain angletoward the base 300 e, the second screw 920 contacts the second holder220 to support the second holder 220. Therefore, the second screw 920can prevent the second holder 220 from continuing to rotate downward andthereby avoid the rotation angle of the hinge 230 from exceeding theallowable range and ultimately prevent the hinge 230 from being broken.

FIG. 28 is a partial perspective view of the mixed reality assemblyaccording to some embodiments of the present disclosure. The maindifference between the present embodiment and the above-mentionedembodiments is that the mixed reality assembly further includes a thirdholder 240 on the second holder 220 and a cover lens 250 on the thirdholder 240. The third holder 240 is connected to the top edge of thesecond holder 220 and extends along a direction substantiallyperpendicular to the second holder 220. The cover lens 250 is disposedon the top surface of the third holder 240. In some embodiments, thecover lens 250 is arranged demountably with the third holder 240. Forexample, the cover lens 250 is magnetic, and the third holder 240 has amagnet 260. Therefore, the cover lens 250 can attach to the third holder240 by magnetic attraction.

FIG. 29 illustrates an enlarged view of a partial region R shown in FIG.28. As shown in FIGS. 28 and 29, the cover lens 250 has a sidewall 251and a slot 252 formed in the sidewall 251. Therefore, the user caninsert a tool or a fingertip into the slot 252 and exert an upward forceon the cover lens 250. When the upward force applied by the user isgreater than the force of the magnetic attraction of the cover lens 250and the magnet 260 (see FIG. 28), the cover lens 250 and the thirdholder 240 can be separated.
